How NOT to get COVID-19

This was a tweet which has been Re-tweeted 100.000 times in two days,

[the advise, how NOT to get COVID-19 infected] made by a (Prof) Takayuki Miyazawa(宮沢孝幸准教授) of the Virus study, Kyoto Uni’, Japan

(1) Think, you were a person already infected by the COVID-19.

(2) And Think, try NOT to infect others.

(3) Breath through the Nose. (not by the mouth)

(4) Don’t touch your Nose, Eyes, Mouth while you are out.

(5) While you are eating, just eat, NOT to SPEAK (or Talk)

(of course, those MIND-SET were on top of the ordinary precaution = What to DO, such as [Wash your hand] [Keep a distance to each other] etc ——- may be because of those mind set and the attitude, the number of the infected in Japan is (on 30-03-2020) only 2.700 cases so far.

Stay safe and keep you well.

A kind of Tree

It seems most of those trees are Oregon Maple in their winter guise.

The lens used was homemade NZ-B lens on the Nikon Z7

Now the street was deserted —– may be because of the spread of the COVID-19, which was said to be 8.000 cases, 400 death in this country, — what can I say.

Why less COVID-19 in Japan ?

The world is wondering why the number cases of COVID-19 in Japan was far less than the other country despite their society has also very aged population like Italy and having a lots of Chinese visitors ?

The observations made by the net people and me were, (1) Japanese is not a kind of people of hug and kiss but make a bow while standing meters away. Because of they are very conscious about the hygiene, which was originated from their Shinto religion which demand the absolute cleanness. ( Non-Japanese may not know that in behind, they clean their hand with wet tissue after made a shake hand with others, and wash the hand after touch the bank note. —– Taking off their shoes on the door step typify the base line, so does eating the individually served food with a chopstick. ) (2) In the same context, when Japanese came back to their home, first they wash their hand and gurgle with plenty water. Then take a bath to wash off any filth remained on the body. (Then, time to time they visit the Shinto Shrine to cleanse and purify their spirit.)

All those almost imprinted into their subconsciousness level of the Japanese ethos which was avoid touching foreign body or not to have a close contact with it, naturally prevented the spread of the virus from the begining. = Japanese didn’t need to be told to do so by the government but doing it by themselves without even aware of it ! (While having this metality deep in their mind, to adapt the Zen idea of Mushin = Mind of nomind has no dificulty to them at all)

While having even the Olympic Game postponed due to the many of the country couldn’t have their own athletes selected through the competition neither able to have enough training, the effect to the Japanese socioeconomic situation is immesurable.

So far, mentally, the Japanese seems to cope with the situation, but having no income from their closed down shop or factory, life is hard. Now, how Japanese government could navigate this situation is the burning issue. (The situation in China is even worse, in any moment they could have national scale violent uprising started which could disintegrates their communist government.) >>>https://www.youtube.com/watch?v=b27T9jHMzb8 >>>https://www.youtube.com/watch?v=iLKuStsHuJI >>>https://www.youtube.com/watch?v=PonD6sTbO3M

——— I received many phone calls from the friends who is anxious about me = thank you very much to all of you = may be I’m the oldest person (except to the OBs of my Japanese Alpine Club) and seen to be the most vulnerable link in the circle though, thanks goodness, so far I’m OK.

——- One of my friend said that he did have the COVID-19 and recovered = when having had it, he said that he noticed that he got his sense of smell and the taste were lost. (and now regained them) = = = So, if you noticed such symptom on top of temperature, coughing etc, it must be the C-19 = Prepare against it ! (either go to a doctor or take a good treatment) —– TAKE CARE !

Spring Equinox 2020

The photos here were taken by NZ-B lens on Nikon Z-7
But this one was by Pentax 110 24mm lens on Sony A7R-IV

Whether the day was something special or not, when it was dull, photo would be dull. Especially when it was taken by the dullest NZ-B lens. (Still, I think, even if the lens was genuine Nikkor or Pentax 110 lens, the sky like this will be looks like dull —– What else ? )

By NZ-B lens

Whether western people feels it is not so special, Japanese cerebrate both equinox as a national holiday. (春分の日、秋分の日=since those days were related to the rice growing agricultural calender they are important in the Japanese tradition)

The same sky in the evening, taken by NZ-B lens on Nikon Z7 —– I like this soft tone.
And the same sky, further down in the evening by Pentax 110 24mm on A7R-IV

The sky looks quiet.

3 – 11 Sunrise

Like on the morning of 9-11 in the United States, the sun doesn’t rise straight on 3-11 in Japan.

6:51 / This photo was taken by the Pentax 110 Auto 24mm lens on Sony A7R IV

And I saw it the same in here.

7:06 / P-24mm on A7RIV
6:55 / Distagon 18mm on D850
6:57 / Godo lens on N-Z7
7:03:05 / Godo lens on N-Z7
7:03:22 / Godo lens on N-Z7
7:05 / Distagon 18mm on D850
7:03:22 / Godo lens on N-Z7
7:07 / Godo lens on N-Z7
7:59 / Godo lens on N-Z7

Nine years ago Japn saw its one of the biggest earthquake and the Tsunami. Since then even the sun seems to aboid to see the eye to eye straight. ———-

Yet on the afternoon, it turned out to be a best brilliant day in this spring !

Cherry 2020

This photo was taken by Pla-B lens on NZ-7
by Pla-B too
By Nikkor 50mm F1.2 on Sony A7R4
By Tamron SP 90mm on Sony A7R4
By Mag lens on A7R4
Mag lens
Mag lens

Mag lens

In the south London, we saw almost no frost = rather warmer wet winter. = May be it caused this early Cherry flowers. (I’m not sure of this variety of cherry ?) —– and the other tree = Somei-yoshino also started to open.

This Somei-Yoshino is a month too early. (Taken by Pla-B lens) —– Strange phenomenon of this photo IS, = see this photo while your one eye closed = don’t you feel that the photo looks 3D !

I hope, COVID-19 wouldn’t hit this country too hard nor the locust comes here. ( —– Yet, last July, I knew the very moment, when the 7th seal was opened. )

Early Magnolia 2020

In this post, the photos were taken by a homemade lens Godo Lens, except no.4.
Those photos were taken by Tamron SP 90mm Macro on Nikon Z7.

I featured this flower twice (?) before using another fuzzy lenses. But, it seems the people takes the flower branch home there is no branch left on the lower part of the tree, and made me very difficult to take picture. (So, I needed to resort with something special measure. 😀 )

Those following five pictures were taken by the other homemade lens “Pla-B” Lens” —– though, with the bad weather I trid three times to get a kind of results. 😀

Walk with Godo lens

Among my homemade lens, being as if it was almost ordinary lens, Godo lens is the most remarkable lens. There was no eccentric feature like 1/2, 1/4 lens kind but two ordinary unknown origins lens put together. (yet, one of them came from my friend Gordon = hence Godo lens ) And the lens happened to produce quite normal image (if not a lots of halation) together with quite nice softness. On top of that, thanks to a Chinese helicoid ring, good convenience of close up use.

I went back to the so-called Perpetual Cherry Tree and found that the area was in a construction site. (Tree was still there and seems flowering though)

I’m not sure whether they are bamboo or reed ?
I like a natural looks quality of this macro. (Too sharp image of most of macro makes the flower looks like an animal body parts) – – – Unless the one was a forensic scientist, we may not like to see too sharp detailed flower parts.

For the cost almost nothing homemade lens, I would say, this is the good lens.

Simple Arithmetic

In the previous post, I mentioned the strength of the image and the size of the lens. When the inside-lens was 6mm and the outside was 14mm, of course the image made by the outside-lens would overwhelm the image of the inside-lens. The image made by the inside-lens will almost disappear like a halo caused by the dust.

.

We can calculate the area size of the lens = 3.14 x R x R – – – but we can see just the relative size as 6×6 against 14×14. In the 14×14=196, 6×6 was the inside-lens – – – 196 – 36 = 160 – – – 160 is obviously too much – – – it got to be about 72 (36+36) and the root of 72 = about 8.5mm – – – it’s mean, if the outside-lens was 8.5mm, the area of its ring shaped lens was the same to 6×6 inside-lens —– The image strength should be the same ! (The Bokeh image made by the inside-lens should be as strong as to the outside-lens’s sharper image.)

While restricting the 14mm to 8.5mm size, effect of the outside-lens was reduced = the inside-lens bokeh became more prominent.
This was not just fuzzy lens but rather sharp (kind of) lens and Bokeh lens conbined = therefore it has certain sharp (?) details.

How awkward = like a useless game of Sisyphus. – – – In fact, that was what all about the game I’ve been plying here = making the lenses.

.

And that was what Lord Buddha told to his disciple, for sweeping the garden to Shuri Pantak, knocking the door to Kisa Gotami. – – – – – Why not to me make the lenses. – – – Why not ?

I like the tone (color shift) of this picture. The watercolor paint which the brush was not well washed = its color has been fused or casted. 😀

.

Those images were made on the Nikon Z7 – – – I think, the softness was just right. (Soft mean, the neibouring pxel’s data were spilled out and infused each other hence the edge of the small details disappeared and the color mixed – – – how wide this infusion occur is the depth of the softness. Or the spread of the light. = Bokeh ! )

When the subject was good, any camera can make nice picture. 😀

Pla (B) Lens

Pla Lens (A) was somewhat a kind of flop in my try. —– Then, Zen wouldn’t give up. 😀 Why not to try with a different lens. Anyway, the luck is in a chance encounter (with a suitable character lens)

A lens I found was a single meniscus glass lens which can make the image like this photo —– of course, this lens could be mounted in the centre of much lager lens though, such large lens tend to have rather longer focal length etc etc. So, I decided to make a hole in the centre of this lens and put other one-time use camera lens in that hole. It took only 5 min’ when I made a hole in that plastic magnifier lens, but this time I had to drill a hole into a hard glass lens. If I push too hard, the glass will chip or worse clack altogether. = slow slowly work took half day.

The one-time use camera lens was pretty small. (I used only front lens ) Which makes the image like this. ( = unlike you expected, the centre lens produce the bokeh, and peripheral lens would creates detailed image. )

So, the concentric double lens was mounted on the camera = AND suprisingly, the image came out was rather normal. = the image was just fuzzy mediocre lens kind. (The size of centre lens was 6mm, Outer lens was 14mm which has 4.4 times larger area = in exposure level, the effect of 6mm lens was too small = negligible) (Yet still, the fuzziness wasn’t too bad even though it was far less than what I expected)

I need to get better subject —– image was somewhat similar to the Godo lens.

The fuzzy lens suite for the flower photo. Nobody complain. 😀
